CTL-023 · Financial integrity

Cost to serve including inference is reconciled

The cost the platform reports reconciles to the invoiced cost of the models and the people each month.

IneffectiveTester is not independent
The tester of record is the control owner. A control tested by the team that operates it is not independently tested. This appears on the duties register as a segregation-of-duties conflict, and it is stated here rather than being hidden behind a pass.

EXC-007Inference cost does not reconcile to the provider invoicemediumopen · due Sep 04, 2026

The cost per unit the platform reports is derived from a modeled rate, not from the invoice. The direction is right; the figure is not reconciled.

Remediation
Ingest the provider invoice and reconcile monthly. Until then, label every cost figure as modeled wherever it appears.

What this page is, and what it is not

Read this before quoting a result

The test results on this page are a modeled test history for a modeled estate. They demonstrate the shape of independent control testing — a named tester outside the operating team, a stated sample method, a sample size, a pass and fail count, and evidence citations that resolve into the chain — not the audited results of a live enterprise.

12 of 12 evidence citations on this control resolve to a record in the evidence spine. Every citation resolves; each one links through to the sealed record it refers to.

A control shown as untested has no result at all. Coverage on this platform counts controls that were actually tested; it never counts a control as passing because it was designed.
